• "Cannot load ViewState" after dynamic control changed

  - by Emil D

  In my ASP.NET page I have to dynamically choose and load a custom control, depending on the selected value in a dropdownlist.However I encountered the following problem: When the parameters of the dynamically loaded control are changed, and then the selection in the dropdownlist is changed( thus forcing me to load a different dynamic control the next time the page reloads ), I end up with a "Cannot load ViewState" exception.I assume that this happens because the ViewState is trying to restore the parameters of the old control and it doesn't find it. So , is there any way to stop the viewstate from attempting to restore the state of the non-existig control?

• Creating Dynamic variables from json response

  - by c0mrade

  My JSON response looks like this : {"sample":[{"id":"2","name":"branch name"},{"id":"3","name":"branch name 2"}]} My function looks like this : function getJSONObjects(){ $.getJSON("http://localhost/api/branches", function(data){ $.each(data.sample, function(i,item){ var loc = "branch"; eval("var " + loc + item.id + "=123;"); alert(loc + item.id); }); }); } The idea is to create branch + id object so I can do something with it(create marker on a map), so I tried to assign it any value to see if this was working. I wanted both branch2 and branch3 to alert 123 so I have something to start with. But currently this alerts branch2 and branch3 instead of 123. I have little experience with creating dynamic variables/objects can someone tell me what I'm doing wrong or maybe another approach towards solving this?

• minimum L sum in a mxn matrix - 2

  - by hilal

  Here is my first question about maximum L sum and here is different and hard version of it. Problem : Given a mxn *positive* integer matrix find the minimum L sum from 0th row to the m'th row . L(4 item) likes chess horse move Example : M = 3x3 0 1 2 1 3 2 4 2 1 Possible L moves are : (0 1 2 2), (0 1 3 2) (0 1 4 2) We should go from 0th row to the 3th row with minimum sum I solved this with dynamic-programming and here is my algorithm : 1. Take a mxn another Minimum L Moves Sum array and copy the first row of main matrix. I call it (MLMS) 2. start from first cell and look the up L moves and calculate it 3. insert it in MLMS if it is less than exists value 4. Do step 2. until m'th row 5. Choose the minimum sum in the m'th row Let me explain on my example step by step: M[ 0 ][ 0 ] sum(L1 = (0, 1, 2, 2)) = 5 ; sum(L2 = (0,1,3,2)) = 6; so MLMS[ 0 ][ 1 ] = 6 sum(L3 = (0, 1, 3, 2)) = 6 ; sum(L4 = (0,1,4,2)) = 7; so MLMS[ 2 ][ 1 ] = 6 M[ 0 ][ 1 ] sum(L5 = (1, 0, 1, 4)) = 6; sum(L6 = (1,3,2,4)) = 10; so MLMS[ 2 ][ 2 ] = 6 ... the last MSLS is : 0 1 2 4 3 6 6 6 6 Which means 6 is the minimum L sum that can be reach from 0 to the m. I think it is O(8*(m-1)*n) = O(m*n). Is there any optimal solution or dynamic-programming algorithms fit this problem? Thanks, sorry for long question

• Dynamic Like Statement in SQL

  - by Peter McElhinney

  Hey there! I've been racking my brain on how to do this for a while, and i know that some genius on this site will have the answer. Basically i'm trying to do this: SELECT column FROM table WHERE [table][column] LIKE string1 OR [table][column] LIKE string2 OR [table][column] LIKE string3... for a list of search strings stored in a column of a table. Obviously I can't do a like statement for each string by hand because i want the table to be dynamic. Any suggestions would be great. :D EDIT: I'm using MSSQL :(

• What is the best way to have a dynamic dropdownlist in PHP and POST selected value

  - by mouthpiec

  Hi, I am writing the following in PHP: i would like to have 2 dropdownlists, where the second one is populated from a mySQL dB according to the choice made on the first dropdown list. Then I would like to use the values of the selected values of the dropdownlist to call another PHP page in which I will generate a db query. Eg: List A: Car Manufactures (honda, nissan, etc) List B: Models (accord, civic, etc) Then I will have a submit button, to POST the values in another PHP file? (I have the basics of how to perform the above without having a dynamic list, but I tried this with AJAX, but I am having problems to pass the value of the second dropdownlist) Any tips of how I can perform the above?

• The Current State Of Serving a PHP 5.x App on the Apache, LightTPD & Nginx Web Servers?

  - by Gregory Kornblum

  Being stuck in a MS stack architecture/development position for the last year and a half has prevented me from staying on top of the world of open source stack based web servers recent evolution more than I would have liked to. However I am now building an open source stack based application/system architecture and sadly I do not have the time to give each of the above mentioned web servers a thorough test of my own to decide. So I figured I'd get input from the best development community site and more specifically the people who make it so. This is a site that is a resource for information regarding a specific domain and target audience with features to help users not only find the information but to also interact with one another in various ways for various reasons. I chose the open source stack for the wealth of resources it has along with much better offers than the MS stack (i.e. WordPress vs BlogEngine.NET). I feel Java is more in the middle of these stacks in this regard although I am not ruling out the possibility of using it in certain areas unrelated to the actual web app itself such as background processes. I have already come to the conclusion of using PHP (using CodeIgniter framework & APC), MySQL (InnoDB) and Memcached on CentOS. I am definitely serving static content on Nginx. However the 3 servers mentioned have no consensus on which is best for dynamic content in regards to performance. It seems LightTPD still has the leak issue which rules it out if it does, Nginx seems it is still not mature enough for this aspect and of course Apache tries to be everything for everybody. I am still going to compile the one chosen with as many performance tweaks as possible such as static linking and the likes. I believe I can get Apache to match the other 2 in regards to serving dynamic content through this process and not having it serve anything static. However during my research it seems the others are still worth considering. So with all things considered I would love to hear what everyone here has to say on the matter. Thanks!

• Intercepting static and dynamic links using javascript

  - by soren.qvist

  Hi, I'm currently developing an ajax application and I'm looking for a feature that lets me intercept all static and dynamic links using javascript. The links look like these: <a href="link1/">link 1</a> <a href="link2/">link 2</a> etc. I then want the browser to redirect to: current.page/#link1/ rather than current.page/link1/. I'm using jQuery, so the live() function is an option, however using that as a solution just seems rather sluggish to me(am I hysterical?). If there is a way to intercept ALL links on a page, maybe through detecting a change in the address, that would greatly help. I've tried a few plugins for jQuery (jQuery address & SWFaddress) but they only seem to have event handlers that respond to changes in anchor tags in the address. Any ideas? thanks for your time

• Dynamically writing out li with jquery. Element is not clickable after being written

  - by estern

  I have have a a function that when a checkbox is checked i dynamically write out an li into a ol that is empty. Code: $(":checkbox").click(function() { var checkedState = $(this).is(':checked'); if (checkedState == true) { var productName = $(this).attr("title"); $("#selectedProductsList").append("<li class=\"productList " + this + "\"><p class=\"removeIcon\"><img src=\"images/remove-icon.png\" alt=\"Remove Product\" /></p><span class=\"productName\">"+ productName +"</span></li>"); }; }); Then when that writes out there is a remove icon that will remove the item from the ol when clicked. This remove icon has a class of removeIcon which can be seen in the dynamic li above. I have a function that processes the remove call and then does some actions: Code: $('.removeIcon').click(function() { alert("starting"); }); Right now i have the remove action just trying to alert a message that it got called. But it seems that it is not getting into the function. Is there a certain way that i need to access these dynamic li's other then the .click method? I saw this post: Dynamically Inserted DOM Elements are not Clickable using $.click() Where they added .live vs .click but this doesn't seem to work either. Any ideas?

• Create dynamic view with android

  - by ekevin

  Hi I'm stuck on a problem and if possible I will need help from the community. I'm not looking for a ready-made solution, but something which would help me to produce the result. I'm looking for a way to produce a dynamic activity based on a JSON object. Here an example of a JSON object: [ { "name": "my checkbox name", "type": "checkbox", "value": "one,two,three" } { "name": "my edit text", "type": "text", "value": "" } ...] This JSONObject could be totally random. I could have 2 text views, 3 select menus, 1 text view and so on. The goal is to iterate over this JSONObject and create the appropriate elements within my android code. To produce the result I've thought of a simple switch which would render one by one my different JSONObject to an android widget. But after that how could I have access of every property of every widget rendered? Thank you.

• Dynamic path in new.AjaxRequest with Rails

  - by Robbie

  Hello, I was wondering if there's anyway to get a 'dynamic path' into a .js file through Ruby on Rails. For example, I have the following: new Ajax.Request('/tokens/destroy/' + GRID_ID, {asynchronous:true, evalScripts:true, onComplete:function(request){load('26', 'table1', request.responseText)}, parameters:'token=' + dsrc.id + '&authenticity_token=' + encodeURIComponent(AUTH_TOKEN)}) The main URL is '/tokens/destroy/:id', however on my production server this app runs as a sub folder. So the URL for this ajax call needs to be '/qrpsdrail/tokens/destroy/:id' The URL this is being called from would be /grids/1 or /qrpsdrail/grids/1 I could, of course, do ../../path -- but that seems a bit hackish. It is also dependent on the routing never changing, which at this stage I can't guarantee. I'm just interested in seeing what other solutions there might be to this problem. Thanks in advance :)

• Flash Displaying Weird Text in a Dynamic Text Field

  - by Andrew M

  I am working in Flash CS5 and I have placed a text field (dynamic, classic text) on the stage. I am accessing it through Actionscript on the same frame like this: var ct:TextField = TextField(getChildByName("Temperature")); ct.text = "Hello world"; What ACTUALLY appears is this: eo wor So... The H, Ls, and D are gone. Mysteriously. Without warning. I am sitting here utterly confused. Is this just me? PS. The text field is set to Myriad Pro Bold, a font on my computer, so it isn't like it's a font problem.

• Java - How to change context root of a dynamic web project in eclipse

  - by Yatendra Goel

  I have developed a dynamic web project in eclipse. Now I can access it through my browser using the following url: http://localhost:8080/MyDynamicWebApp Now I want to change the access url to http://localhost:8080/app I changed the context root from the project properties | Web Project Settings | Context Root But it is not working. The web app still has the access url as earlier. I have re-deployed the application on tomcat, re-started the tomcat and have done everything that should be done but the access url is the same as earlier. I found that there were no server.xml file attached with the WARfile. The how the tomcat is determining that the context root of my web app is /MyDynamicWebApp and is allowing me to access the application through that url

• Direct flow depending on incoming dynamic type

  - by Improfane

  I have a listener class that accepts GUI change events in one method. The incoming event objects have a superclass of a type of GUI Event, the behaviour should depend on the dynamic type of the incoming variable. I wanted to do do lots of methods like: handleGUIEvent(EventChangedX event) handleGUIEvent(EventChangedY event) I am using a single event listener and receiving objects of various types but the behaviour should be different for each. What would you do? I do not want to use a switch statement as this would get unmaintainable.

• How to Implement Dynamic Timestamp in Web Page?

  - by Morgan Cheng

  In Facebook and twitter, we can see that there is a timestamp like "23 seconds ago" or "1 hour ago" for each event & tweet. If we leave the page for some time, the timestamp changes accordingly. Since it is possible that user machine doesn't have same system time as server machine, how to make the dynamic timestamp accurate? My idea is: It is always based on server time. When request is sent to server for the web page, timestamp T1 (seconds to 1970/1/1) is rendered into inline javascript variable. The displayed timestamp ("23 seconds ago") is calculated by T1 instead of local time. I'm not sure whether this is how Facebook/Twitter do it. Is there any better idea?

• Using *.html extension in dynamic URL's for SEO

  - by lostaman

  Hi all My situation is. I have a project planned to be built on ASP.NET MVC 2. And one of the major requirements is SEO optimization. A customer wants to use static-like URLs that end up with .html extension for this project that make URLs more SEO friendly. E.g. "mysite.com/about.html " or "mysite.com/items/getitem/5.html" etc. I wonder is there any benefit from SEO perspective to use .html extension in dynamic URLs? Are Google and other search engines rank work better with such URLs?

• dynamic broadcast receiver for connectivity changes

  I'm trying to register a dynamic broadcast receiver using the following: BroadcastReceiver connectivityReceiver = new ConnectivityChangeIntentReceiver(); IntentFilter connectivityFilter = new IntentFilter(); filter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION); filter.addAction(android.net.ConnectivityManager.CONNECTIVITY_ACTION); myApplicationContext.registerReceiver(connectivityReceiver, connectivityFilter); but I see my ConnectivityChangeIntentReceiver.onReceive method is not called when I turn off Wifi through settings or change to airplane mode. Has anyone faced a similar problem? I do not want to statically register the receiver in the Manifest file, as I don't want my app to be started by connectivity changes.

• Dynamic Custom Fields for Data Model

  - by Jerry Deng

  I am in the process of creating a dynamic database where user will be able to create resource type where he/she can add custom fields (multiple texts, strings, and files) Each resource type will have the ability to display, import, export its data; I've been thinking about it and here are my approaches. I would love to hear what do you guys think. Ideas: just hashing all the custom data in a data field (pro: writing is easier, con: reading back out may be harder); children fields (the model will have multiple fields of strings, fields of text, and fields for file path); fixed number of custom fields in the same table with a key mapping data hash stored in the same row; Non-SQL approach, but then the problem would be generating/changing models on the fly to work with different custom fields;

• Dynamic Dropdown menu through php

  - by Code_Ed_Student

  I visited a website a few weeks ago and came across a dynamic drop down menu. I came across a functionality that I am now trying to replicate but do not know how. In the dropdown you picked the desired number of cars and then it reiterated input fields according to the number of cars chosen. I believe this was done through javascript and a loop was involved. Is there a term for this action or way to display things? Also an example of how to accomplish something similar would help?
